Error Message When You Insert an Audio CD

After you install and then uninstall a third-party audio CD player by using the Add/Remove Programs tool in Control Panel, inserting an audio CD does not cause the CD to start playing automatically. When you insert an audio CD, you may receive the following error message:

The error message occurs because the third-party audio CD player alters the path for the program to play CDs automatically. Uninstalling the third-party audio CD player with the Add/Remove Programs tool does not replace the path to the CD Player program that is included with Windows 2000.
